As recorded:
Dongchuan District, Kunming Prefecture, Yunnan Province  China
Dimensions

Description
New on the market in 2022. Botryoidal growths of Aragonite, very aerial, translucent and with an intense blue color due to inclusions of copper salts. Curiously, its duller green matrix is Calcite instead of Aragonite, as analysis surprisingly showed the presence of both polymorphs in the same piece.
